What are the merits and demerits of water tube boiler?
Disadvantage:
| SL NO | Disadvantage |
|---|---|
| 1. | Complex design and High maintenance cost. |
| 2. | A skilled operator is required for operation. |
| 3. | This is used in large power plants and it is uneconomical for use in small industries. |
| 4. | For the same power output, the cost of a water tube boiler is high. |
What are the disadvantages of fire tube boiler?
Fire Tube Boiler Disadvantages: The fluctuation of load cannot be easily handled. The rate of steam generation is low. A Fire boiler is used in small power plants. The maximum working pressure is up to 20 bar which is a less comparatively water tube boiler.
What are the advantage and disadvantage of water tube boiler over the fire tube boiler?
| Fire Tube Boiler | Water Tube Boiler |
|---|---|
| The overall efficiency of this boiler is up to 75\% | The overall efficiency is up to 90\% with the economizer |
| Water doesn’t circulate in a definite direction | Water circulates in a well – defined direction |
What are the disadvantages of water tube boiler?
Disadvantages of a water tube boiler:
- It is necessary to be more careful with the quality of the feed water.
- More complex control systems are needed for the drum level due to the smaller water spaces.
- Operators must be faster when there is an alteration because everything happens faster with a water tube boiler.
What is difference between water tube boiler and fire tube boiler?
The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam.
Which is fire tube boiler?
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
What is advantage of fire tube boiler?
Fire tube boilers are a lower cost alternative to water tube boilers and are often used for smaller industrial facilities with lower operating pressures. The main advantages of a fire tube boiler are its simple construction, compact size and the ability to easily meet rapid fluctuations in steam demand.
What is advantage of water tube boiler?
Advantages of water-tube boilers: They have a small water content, and therefore respond rapidly to load change and heat input. The small diameter tubes and steam drum mean that much higher steam pressures can be tolerated, and up to 160 bar may be used in power stations.
How does a fire tube boiler work?
A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
What is the function of fire tube boiler?
What are the advantages and disadvantages of fire tube boilers?
May 16, 2006 – Advantages of fire tube boilers: – More residual heat in the water to allow for Disadvantages of a Water Tube Boiler – Must be more careful of Water tube boilers. Class of Steam boiler in which water flows inside the tubes and hot gases surround the tubes are called as water tube boilers.
What is the treatment of feed water in fire tube boiler?
Treatment of feed water is not very essential in fire tube boiler. 5. No pure feed water is required in FTB, So cost can be minimized because pure feed water is costly. 6.
What are the different types of boilers?
The examples of this boiler are the simple vertical boiler, Cochran boiler, Lancashire boiler, Cornish boiler, Locomotive boiler, Scotch marine boiler and Velcon boiler. 1. Fire tube boiler is in simple design and has a low maintenance cost.
What is an example of a vertical boiler?
The heat from the hot gases is conducted through the walls of the tube to the water. The examples of this boiler are the simple vertical boiler, Cochran boiler, Lancashire boiler, Cornish boiler, Locomotive boiler, Scotch marine boiler and Velcon boiler.
